cache.add()/addAll() fully read the response body (to avoid hanging, nodejs#5615/nodejs#5844), which disturbs the stored response's stream. A later cache.match()/matchAll() then tees that disturbed stream in cloneBody() and throws `ERR_INVALID_STATE: ReadableStream is locked`. Rebuild a fresh, regenerable body from the bytes read in processResponseConsumeBody, mirroring how Cache.put stores body.source. Fixes nodejs#5859 Signed-off-by: DevGnott <strelov.andre98@gmail.com>

Fixes #5859
Rationale
cache.add()/cache.addAll()fully read the response body while storingit (added in #5844 to avoid the hang from #5615). Reading disturbs the stored
response's stream, so a later
cache.match()/cache.matchAll()tees adisturbed stream in
cloneBody()and throwsTypeError [ERR_INVALID_STATE]: Invalid state: ReadableStream is locked.Cache.put()doesn't hit this because it stores the read bytes asbody.source. This applies the same idea to the add/addAll path.Changes
In
processResponseConsumeBody, rebuild a fresh, regenerable body from thebytes that were just read, so the stored response can be cloned later.
